Okay, now that I've merged your tree, we've moved a few steps forward but
a couple of steps backward with LDP support:

1. LDP LCD platform device added
2. GPIO keyboard platform data added
3. TWL4030 keyboard platform data added
4. TSC2046 touchscreen platform data added
5. MMC has regressed - no sign of the driver initializing, not even an
   error message from it, so I can't boot to check what the status of
   these are.
6. do ___NOT___ (underscored in triplicate and 500ft high letters) enable
   ARM errata 460075 - it solidly prevents the kernel booting on LDP.
   (it's taken many hours to debug that.)

However, things that still seem to be missing:

1. GPIO keyboard (presumably) needs to be enabled in omap_ldp_defconfig
2. No TWL4030 keyboard driver merged (not even in linux-next)
3. No LDP LCD driver merged
4. No OMAP3 video driver
5. No sound?

Any ideas what's happening with these?  Will they make the next merge
window (which is possibly about a week away) - I guess not. :(
